The Alvarez hypothesis claims that an asteroid caused what event?
Answer The extinction of the dinosaurs
Father-son geologist team Luis and Walter Alvarez theorized that an asteroid struck earth in Chicxulub, Mexico, and evidence found in a crater there supported this hypothesis. This theory has led to the belief that the Chicxulub asteroid caused mass extinction, including dinosaurs.
